Rather, these embodiments are provided so that this invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0035] It should be understood that the terminology used herein is for the purpose of describing particular exemplary embodiments only and is not intended to be limiting. Unless the context clearly indicates otherwise, the singular forms “a,” “an,” and “described” as used herein may also include the plural forms. The terms “comprising,” “including,” “containing,” and “having” are inclusive and therefore indicate the presence of the stated features, steps, operations, elements, and / or components, but do not exclude the presence or addition of one or more other features, steps, operations, elements, components, and / or combinations thereof. The method steps, processes, and operations described herein are not construed as requiring them to be performed in a particular order described or illustrated unless the order of performance is explicitly indicated. It should also be understood that additional or alternative steps may be used.

[0036] Although terms such as first, second, third, etc., may be used in this document to describe multiple elements, components, regions, layers, and / or segments, these elements, components, regions, layers, and / or segments should not be limited by these terms. These terms may be used only to distinguish one element, component, region, layer, or segment from another. Unless the context clearly indicates otherwise, terms such as "first," "second," and other numerical terms used herein do not imply order or sequence. Therefore, the first element, component, region, layer, or segment discussed below may be referred to as the second element, component, region, layer, or segment without departing from the teachings of the exemplary embodiments.

[0037] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a connection that allows communication between the components; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0038] For ease of description, spatial relative terms may be used in the text to describe the relationship of one element or feature relative to another element or feature, as shown in the figure. These relative terms include, for example, "inside," "outside," "middle," "outer," "below," "below," "above," "over," etc. Such spatial relative terms are intended to include different orientations of the device in use or operation, other than those depicted in the figure.

Therefore, the example term "below" can include both upper and lower orientations.

[0039] According to an embodiment of this utility model, a top cover assembly is proposed, comprising a top cover 20, a control plate 30, and a water guide channel 40. A splicing point 101 is provided between the top cover 20 and the control plate 30. The abutting connection between the top cover 20 and the control plate 30 makes the top of the housing 1 flatter and reduces the possibility of dust and moisture entering the housing 1. The water guide channel 40 is connected to one of the top cover 20 and the control plate 30, and is located below the splicing point 101. The water outlet 401 of the water guide channel 40 is connected to the water outlet 102. When water accumulated on the top of the enclosure 1 leaks into the interior of the enclosure 1 through the joint 101, it will flow into the water guide channel 40. Guided by the water guide channel 40, the water will flow out of the interior of the enclosure 1 through the outlet 401 of the water guide channel 40 and the outlet 102 formed between the side panel 10 and the control panel, thereby achieving waterproofing between the top cover 20 and the control panel 30 and effectively protecting the electronic components and hardware equipment inside the enclosure 1.

[0040] The connection method between the water guide channel 40 and the top cover 20 or the control plate 30 can be selected according to the material and structure of the top cover 20 and the control plate 30. For example, the connection between the water guide channel 40 and the top cover 20 can be achieved by welding, bonding or bolting.

[0041] It should be noted that the joint 101 between the top cover 20 and the control panel 30 is not a reserved gap, but a gap that will inevitably be generated after the top cover 20 and the control panel 30 are joined together. Therefore, a water guide channel needs to be set to guide the water that leaks into the box from the joint 101 to the outside of the box.

[0042] In this embodiment, as Figure 1 and Figure 2As shown, the water guide channel 40 and the top cover 20 are integrally injection molded components. This integrated design eliminates any seam 101 between the water guide channel 40 and the top cover 20, further improving the waterproof performance of the top of the enclosure 1. The water guide channel 40 is located at the end of the top cover 20 facing the control panel 30. The water guide channel 40 includes a top section 41 and two side sections 42 connected to both ends of the top section 41. The top section 41 extends along the length of the seam 101 to ensure that all water leaking from the seam 101 is collected by the top section 41. The side sections 42 are curved relative to the top section 41 towards the bottom of the enclosure 1, allowing water to flow smoothly to the side sections 42 under gravity. The end of the side section 42 facing away from the top section 41 defines the outlet end 401 of the water guide channel 40, from which water exits the water guide channel 40.

[0043] Furthermore, such as Figure 1 and Figure 2 As shown, the top section includes a first segment 411 and a second segment 412 arranged sequentially along the extension direction. The top section 41 includes a first segment 411 extending from the middle of the top section 41 to the first end of the top section 41, and a second segment 412 extending from the middle of the top section 41 to the second end of the top section 41. The first segment 411 extends inclined towards the bottom of the box 1 along the direction of the second segment 412 toward the first segment 411, and the second segment 412 extends inclined towards the bottom of the box 1 along the direction of the first segment 411 toward the second segment 412. Each of the first segment 411 and the second segment 412 has a side segment 42 at one end that is opposite to each other. The inclined design of the first segment 411 and the second segment 412 makes the top section 41 present a shape that is high in the middle and low at both ends, so that the water leaking from the splice 101 flows more quickly to the two ends of the top section 41, thereby accelerating the process of water entering the side segment 42 and finally being discharged from the box 1. Compared to the horizontal top section 41 design, the inclined top section 41 can more effectively guide the flow of accumulated water using gravity, improving drainage efficiency. Due to the inclined design of the top section 41, water will not accumulate in the middle of the top section 41, but will quickly flow to both ends. This can prevent water from staying in the water guide channel 40 for too long, reducing the risk of water leakage into other parts of the tank 1.

[0044] In some embodiments, please combine Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7As shown, the control panel 30 includes a front panel 31 and a top panel 32 connected together. The front panel 31 is located at the top of the housing 1 facing forward, and extends vertically to mount the control panel of the garment processing equipment for user operation. The front panel 31 is spaced apart from the top cover 20. The top panel 32 is located between the front panel 31 and the top cover 20, and extends horizontally and is flush with the top cover 20. The top panel 32 abuts against the end of the top cover 20 facing the control panel 30, forming the aforementioned splice 101 between the top panel 32 and the top cover 20. The connection between the top section 41 of the water guide trough 40 and the top cover 20 forms an upward-facing stepped surface 413. The top panel 32 of the control panel 30 abuts against both the top cover 20 and this stepped surface 413. That is, the side of the top panel 32 facing the top cover 20 in the horizontal direction is closely fitted to the top cover 20, and the side of the top panel 32 facing downward in the vertical direction is closely fitted to the step surface 413, so that the control plate 30, the top cover 20 and the water guide groove 40 form a relatively tight connection.

[0045] The tight fit between the top panel 32 and the top cover 20, as well as the stepped surface 413, ensures a more stable connection between the control plate 30 and the top cover 20. This reduces relative displacement between the control plate 30 and the top cover 20 during vibration or impact of the enclosure 1, thus improving the overall structural stability of the enclosure 1. Furthermore, the abutment between the top panel 32, the top cover 20, and the stepped surface 413 effectively reduces gaps between the control plate 30 and the top cover 20, thereby enhancing the sealing of the top of the enclosure 1 at the connection between the control plate 30 and the top cover 20. Moreover, the stepped surface 413 provides a clear positioning reference for the installation of the control plate 30. When installing the control plate 30, simply ensuring accurate fit between the top panel 32, the top cover 20, and the stepped surface 413 guarantees the correct installation position of the control plate 30, improving installation efficiency and accuracy.

[0046] In some embodiments, please combine Figure 3 , Figure 6 and Figure 7 As shown, the control panel 30 also includes multiple support arms 34. The multiple support arms 34 are arranged sequentially and spaced apart along the length of the top section 41. The support arms 34 are connected to the front panel 31. The end of the support arm 34 away from the front panel 31 extends to the bottom of the top section 41, that is, the support arm 34 extends from the front panel 31 to the rear. In a direction perpendicular to the top panel 32, the support arm 34 and the top panel 32 are spaced apart, and the support arm 34 and the top panel 32 together clamp the top section 41. The top panel 32 abuts against the stepped surface 413 of the top section 41 from above, while the support arm 34 approaches the lower surface of the top section 41 from below. Through the space between the two, a certain clamping force is formed on the top section 41, and the control panel 30 is fixedly connected to the top cover 20.

[0047] In this embodiment, the top section 41 is clamped together by the support arm 34 and the top panel 32, which effectively fixes the control plate 30 and the top cover 20 as a whole. This ensures that the relative position of the joint 101 between the control plate 30 and the top cover 20 and the water guide channel 40 is stable and reliable, fixing the position of the water guide channel 40 in the housing 1 and preventing displacement of the water guide channel 40 relative to the joint 101 during use. This ensures that the water guide channel 40 can perform its drainage function normally, improving the stability and reliability of drainage. Furthermore, the support arm 34 increases the structural strength of the control plate 30, enabling it to better withstand external pressure and impact. At the same time, the support arm 34 and the top panel 32 clamp the top section 41 of the water guide channel 40 together, making the connection between the control plate 30, the water guide channel 40 and the top cover 20 tighter, further enhancing the overall structural strength of the housing 1.

[0048] In some embodiments, such as Figure 7 , Figure 8 and Figure 9 As shown, the control panel 30 also includes two connecting arms 35, which are connected to the front panel 31. The connecting arms 35 are configured to securely support the control panel 30. One end of the connecting arm 35, facing away from the front panel 31, extends between the top cover 20 and the side panel 10, and connects to the side panel 10. The connecting arms 35 strengthen the connection between the control panel 30 and the side panel 10 of the housing 1, making the installation of the control panel 30 in the housing 1 more stable. This stable connection improves the overall structural strength of the housing 1, enabling it to better withstand external pressure and impact, and reducing deformation or damage to the housing 1 caused by external forces. The end of the side section 42 facing away from the top section 41 abuts against the connecting arm 35.

[0049] Furthermore, such as Figure 7 , Figure 8 and Figure 9 As shown, the control panel 30 also includes two side panels 33, which are located on either side of the top panel 32 and the front panel 31, respectively. The side panels 33 are connected to the top panel 32 and the front panel 31, respectively. The two side panels 33 are flush with the two side panels 10, making the overall appearance of the housing 1 more concise and beautiful. A drainage groove 37 is also provided between the connecting arm 35 and the side panels 33. The drainage groove 37 has drainage holes 36, which are connected to the water outlet 401 and the water outlet 102, respectively.

[0050] The drainage channel 37 is used to guide and collect accumulated water. Water flowing from the outlet 401 of the water guide channel 40 first enters the drainage channel 37, and then is discharged through the drainage hole 36 within the drainage channel 37 to the outlet 102 formed between the side panel 10 and the control plate, thereby draining the water from the top of the tank 1 to the outside of the tank 1. The drainage channel 37 provides a centralized discharge area for the accumulated water, allowing it to flow more orderly towards the drainage hole 36. This improves drainage efficiency, ensuring that the water on the top of the tank 1 can be quickly discharged, reducing water accumulation inside the tank 1. The combination of the drainage channel 37 with the side panel 33 and the connecting arm 35 further optimizes the structural design of the tank 1, making the connections between various components more reasonable and improving the overall performance of the tank 1. The drainage hole 36 provides a clear discharge channel for the water in the water guide trough 40. By connecting the drainage hole 36 to the water outlet 401 of the water guide trough 40 and the water outlet 102 formed between the side plate 10 and the control plate, it ensures that the water can be discharged from the box 1 quickly and smoothly. This effectively prevents water from accumulating inside the box 1.

[0051] According to an embodiment of this utility model, a housing is also proposed. Please refer to... Figure 1 , Figure 2 , Figure 3 and Figure 11 As shown, the housing 1 includes a top cover assembly and two side panels 10. The two side panels 10 are arranged opposite each other and spaced apart, providing the main support structure for the housing 1. The space between the two side panels 10 is used to accommodate the rollers of the garment processing equipment, as well as various electronic components and hardware devices. The top cover 20 and control panel 30 are located on the top of the housing 1. The top cover 20 protects the internal components from dust and external damage, while the control panel 30 integrates various control buttons and indicators for the garment processing equipment, facilitating user operation and monitoring. The top cover 20 and control panel 30 are respectively connected to the top of the two side panels 10. The connection can be achieved using a slot and buckle mechanism or by bolts. For example, a slot can be provided on the top edge of the side panel 10, and corresponding buckles can be provided on the edges of the top cover 20 and control panel 30. Connection is achieved by inserting the buckles into the slots. This connection method facilitates installation and disassembly while ensuring connection stability. For example, screw holes are provided at the top edge of the side panel 10 and at corresponding positions of the top cover 20 and control plate 30, and the three are fixed together by bolts. The top cover 20 abuts against the control plate 30, and there is a splice 101 between the top cover 20 and the control plate 30. The abutting connection between the top cover 20 and the control plate 30 can make the top of the box 1 flatter, and at the same time reduce the possibility of dust and moisture entering the interior of the box 1.

[0052] Furthermore, such as Figure 8 , Figure 9 , Figure 10 and Figure 11As shown, the side panel 10 includes a main body panel 11 extending in a first direction and a connecting plate 12 connected to the main body panel 11 and extending in a second direction. The first direction is parallel to the side panel 33, and the second direction is parallel to the top panel 32. The connecting plate 12 is connected to the connecting arm 35. There is a water outlet gap 103 between the connecting plate 12 and the side panel 33. The water outlet gap 103 forms a water outlet 102 on one side of the main body panel 11. When the water in the water guide channel 40 is discharged through the drain hole 36 in the drain channel 37, the water will pass through the water outlet gap 103 and finally flow out of the box 1 from the water outlet 102.

[0053] In this embodiment, the connecting plate 12 is arranged horizontally or at a certain angle to the horizontal direction. On the one hand, the connecting plate 12 provides a plane for connecting the connecting arm 35. Connecting holes are provided on the connecting plate 12 and the connecting arm 35 respectively, and the connecting plate 12 and the connecting arm 35 are connected by bolts. On the other hand, the connecting plate 12 also receives the water discharged from the drain hole 36 and guides it to the outlet 102. By forming a water outlet gap 103 between the connecting plate 12 and the side panel 33, a reasonable channel layout is provided for the drainage of the tank 1. The water can smoothly flow to the outlet 102 through the outlet end 401 of the water guide trough 40, the drain trough 37, the drain hole 36 and the water outlet gap 103 in sequence according to the predetermined path, avoiding confusion and blockage during the drainage process.

[0054] The water outlet gap 103 is designed to make full use of the space between the side plate 10 and the control plate 30, without taking up too much extra space. This compact design enables the tank 1 to achieve efficient drainage within a limited space, while also providing more installation space for other components inside the tank 1.

[0055] This utility model also proposes a clothing processing device, which includes a housing 1, a washing tub, a motor, a water inlet system, a drainage system, and a control panel. Specifically, the washing tub is installed inside the housing 1, and the motor is installed at the bottom or side of the housing 1. The motor is connected to the washing tub via a transmission device to provide power for the rotation of the washing tub. The control panel is installed on the front panel 31 of the control board 30 and is used by the user to operate and set parameters such as washing mode and time. The control panel is connected to other components inside the housing 1 via wires. The water inlet system includes components such as a water inlet pipe, a faucet connection port, and a water inlet valve. The water inlet system is located at the rear or side of the housing 1 and introduces external water into the washing tub. The drainage system includes components such as a drain pipe and a drain pump, and is used to discharge wastewater from the washing machine.

[0056] The clothing handling device proposed in this utility model allows water to seep into the interior of the box 1 from the joint 101 when it accumulates at the top of the box 1. The water then flows into the water channel 40 and, guided by the water channel 40, exits into the interior of the box 1 through the outlet 401 of the water channel 40 and the outlet 102 formed between the side plate 10 and the control plate. This achieves waterproofing between the top cover 20 and the control plate 30, effectively protecting the electronic components and hardware devices inside the box 1.

[0057] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
